The Radio Bari station, broadcasting from Bari in southern Italy, with a power of 20 kW, was commissioned by the Italian national broadcasting company, EIAR, in 1932.
By decision of the Fascist regime, in 1934 Radio Bari started to broadcast propaganda and counter-propaganda programmes, accompanied by music and political commentaries, for listeners in Arabic-speaking countries. These broadcasts, aired at regular intervals from 10.30 a.m. until 3 a.m., were received throughout the Mediterranean basin, reaching countries including Egypt, Palestine, Iraq, Syria, Lebanon, Algeria, Tunisia and Morocco, where British or French influence was at that time predominant. A few months later, the station also began to broadcast in the Greek language. The months that followed saw a true radio war, which lasted throughout World War II, including jamming of radio signals, between the Axis and Allied radio stations.
On 8 September 1943, the Bari transmitter, one of the few still operating in southern Italy, was peacefully occupied by a group of local intellectuals politically close to the philosopher Benedetto Croce together with groups of anti-fascists, republicans, democrats and activists of the Action Party. With the help of some radio technicians, they were able to transmit on 11 September the first message of the King of Italy, Victor Emanuel III, after his departure from Rome. Radio Bari was thus able to broadcast the first broadcast of free Italy. Starting from 23 September 1943, the premises of Radio Bari were occupied by the Americans who immediately made it the organ of their headquarters in Algiers. The core programme was Italia combatte (Italy fights on) in which, while complying with the directives of the Allied Command, the speakers targeted the public opinion of southern Italy with interesting features full of news and testimonies from the front, as well as on guerrilla actions, together with information for partisans and anti-fascist propaganda. These political programmes were supported by "a lot of music for which an entire record store was seized".
